latex in text citations error: citation undefined

I am wanting to do in text citations for my dissertation. I will upload a simplified version of what i am seeing. The issue is that i keep getting "undefined citations" where i only get the citation key out in my pdf irrespective of which compiler i use.

I also keep getting an error saying that the bibliography is empty. But when my friend uses the exact code i have and copies the references and everything into his overleaf environment it works. I could not get it working with miktex and texmaker. Please help

I have checked a lot of articles of what is available and i swear im following what they are doing but i cant get any further

Initially, my idea is to pull the citations from another file because ill be using these citations in multiple documents. I have successfully setup the .bib file which will update as i add more references to Zotero (my reference manager). I tried to pull citations from the .bib file by coding in the file directory, but no luck there.

I then tried to not use the "file directory approach" and just have a references file in the same folder as the .tex file. But that didnt work either.

my code is as follows:

\documentclass[11pt]{article}
\usepackage{geometry}
\usepackage{latexsym}
\usepackage{graphicx}
\usepackage[style=ieee]{biblatex}
\addbibresource{refs.bib} %%updated from References.bib

%%\printbibliography[title = Reference List]
%%\bibliography{MyZoteroLibrary.bib}

\end{document}

EDIT: Upon trying to do what @celdor initially said said i still run into the same issue. The following screenshots add to the initial question. Screenshot showing code and issue directly Screenshot showing Latex "Configure" settings Warnings from Latex in Texmaker

From the Log file, the following logs detail relevant warnings

The answer as suggested by @samcarter_is_at_topanswers.xyz is that I was not using biber.

To do this on textmaker proceed to Options/Configure Textmaker. A configuration window will appear. Under the Commands Window locate "Bib(la)tex" and set the designation to "biber %". This will solve the issue.

Setting Update

A similar procedure can be followed on texstudios

See the below link on how to make sure textmaker uses this setting for reference.

thank you for everyones efforts in solving this problem.

First, latexsym is an old package superseded by amssymb. I looked at the file and its last update was in 1998!

As to your issues, assuming your text file is main.tex, try the following:

  • Clean your project folder from all auxiliary *.aux; the best way to do that is to issue latexmk -C in your project folder.
  • Additionally, remove main.bbl
  • make sure your *.bib file is in the root project folder
  • add backend=biber to list of options of biblatex.

Then, run:

pdflatex main.tex     # or xelatex main.tex or lualatex main.tex etc.
biber main
pdflatex main.tex     # see above

Without *.bbl file, the first run of pdflatex does not produce any reference list and latex may issue a warning. With an old *.bbl file, you will get wrong citations. After the whole sequence is executed, main.pdf should have the correct citation and a reference list.

Remember \bibliography is incompatible with biblatex. The correct macro to create bibliography list is \printbibliography. It will issue \section* in article or \chapter* in report/book for a title and format it according to settings in a document class.

Here, I created References.bib with a dummy article:

@ARTICLE{schmidtPreprocessingMethodologyEnhance2019,
  author  = {Other, Anthony Norman},
  title   = {Some things I did},
  year    = {2014},
  journal = {J.~Irrep. Res.},
  volume  = {1},
  number  = {1},
  pages   = {1-10}
}

and run the code as suggested, and frankly I get expected results without any errors!

The full code:

\documentclass[11pt]{article}
\usepackage{geometry}
\usepackage{amssymb}   %superseds latexsym   
\usepackage{graphicx}
\usepackage[backend=biber,style=ieee]{biblatex}
\addbibresource{References.bib}
